# Step 4: validation-report-handoff

## Read First

Read these files before editing:

- `/AGENTS.md`
- `/docs/PLAN.md`
- `/docs/PROGRESS.md`
- `/docs/WORKNOTE.md`
- `/docs/AGENT_RULES.md`
- `/docs/implementation-plans/property-model-foundation-implementation-plan.md`
- `/phases/property-model-foundation/index.json`

## Task

Record validation evidence and handoff notes after the property model foundation implementation.

Required updates:

- Update `/docs/PROGRESS.md` with completed property base and Domain property ownership work.
- Update `/docs/PLAN.md` only if sequencing or acceptance criteria changed.
- Update `/docs/WORKNOTE.md` only if there were failures, repeated mistakes, or environment traps.
- Mark `/phases/property-model-foundation/index.json` steps and `/phases/index.json` according to actual results.

## Tests To Write First

- Documentation/reporting step. No new C++ test is required.

## Acceptance Criteria

```powershell
python -m unittest discover -s scripts -p "test_*.py"
python scripts/validate_workspace.py
git diff --check
```

## Verification Notes

1. Do not claim MITC4 formulation correctness.
2. Do not claim HDF5 result output is implemented.
3. Keep validation evidence concrete: command, result, and scope.
